Procurement Notes

Verify the specific datasheet version for the WBFK-30111-000 to confirm current manufacturing status and any potential design changes. Ensure that the procurement source provides original manufacturer documentation to guarantee authenticity. Cross-reference the part number with official Knowles catalogs to validate compatibility with existing system requirements before finalizing orders.

Selection Notes

Select this model when a low-impedance (15 Ohms) receiver is required for efficient power consumption in battery-operated devices. The wide frequency response up to 7.4 kHz makes it suitable for voice clarity applications. Consider the rectangular shape and panel mount style if mechanical constraints dictate a specific orientation or mounting method within the enclosure design.

Part Context

This component belongs to the WBFK series of receivers from Knowles, which are known for their durability and acoustic performance. The series includes various models with different impedance and frequency characteristics. The WBFK-30111-000 specifically targets applications needing a balance between size, weight, and audio fidelity, often found in professional and medical audio gear.

Replacement Considerations

Direct substitutes may include other WBFK series variants such as WBFK-30000-000 or WBFK-30042-000, provided impedance and frequency responses match the design requirements. Always verify electrical parameters and physical dimensions before swapping components to ensure proper fit and function.
